Learning from Taiwan modifying activation technology, combined with our own actual experience in powder production, Dongguan Vsunny Machinery Co., Ltd. independently researched and developed deep-processing equipment for surface treatment for a variety of inorganic powder. It will be used to modify the D97≤10μm ultrafine light (heavy) calcium carbonate, or surface treatment of the calcined Kaolin, the production capacity can reach 2.0T~8.0T/h; the activated rate≥96%, and the unit energy consumption≤35kwh/t.

This continuous activation modify & coating machine can be used for dry surface modification of powder of various fineness from 325 mesh to 6000 mesh, such as the surface modification and activation of light calcium carbonate, ground calcium carbonate, washed kaolin, calcined coal kaolin, talcum, quartz powder, mica, aluminum hydroxide, magnesium hydroxide and brucite, ultrafine and precipitated barium sulfate, lithopone, white carbon black, titanium dioxide, coal ash, sericite, zinc oxide and other materials, while at the same time it can depolymerize and scatter the materials

Working principle

The unit accomplishes the surface treatment of power mainly by means of three “Triangle” modification cylinders. The dry powder and accurately measured reagents were put into the cylinders together, ran in fluidization with the high-speed rotation of rotor, modified rapidly through the collision, friction and shear of the high-speed running powder and the heat produced by the high-speed rotating rotor.

.1.The unit can work continually with a huge processing capacity, suitable for all scales of industrial production. Around 3000 tons can be actively modified each month for 1250 meshes of powder.

2.The modification reagents have a high usage rate, small consumption (around 0.5% to 1% of activation reagents consumption), high powder coating rate and activated rate, and low energy consumption.

3.The equipment has both modification and depolymerization functions. It is proper for all kinds of material sizes, and has a special modification, activation & coating effect on material with small density and big visual rate, such as barium sulfate, silica, mica powder and talcum powder.

4.The machine adopts a special and mixed cold powder and hot reagents high-speed gas-solid phase vortex type operation mode. The mode has high modification efficiency and will not destroy the original shape of the powder.

5.The material is processed under negative pressure with good sealing. No leak of the powder, no pollution; good operational environment; low labor intensity.

6.The cooling and heating processing can be accomplished in the same machine. No independent heating or cooling system is required. The operation is simplified.

7.Independent liquid and non-liquid dosing system. The dosing is continual, stable and even.

8.The continuous activation modify & coating machine is possessed with a mature artificial intelligent control system, with simple and accurate operation. It can be applied to vertical mill computer control system and realizes a perfect connection.

The company is located in the economic center Changping Town in the east of Dongguan City in Guangdong Province. The plant area reaches 15,000 square meters. After many years of research and development, it has already earned more than ten patented technologies and assessed as the " Private Scientific And Technological Enterprise in Dongguan” by the Dongguan Municipal Government and in September 2015 it passed ISO9001: 2008, an international standard for quality management system. In March 2016, we also passed ISO14001:2004 environmental management system certification. At the same time, our company is the only business that can produce single and dual hydraulic vertical mills. Since its inception, under the business goal of “technology is changing the quality, excellence comes from professionalism”, our company has taken the lead in developing and designing a national brand for high-end vertical mill equipment.

We are focused on providing all types of powder manufacturers with a turnkey project comprising a whole set of ultrafine powder production lines, from crushing, transportation, grinding, classifying to the design, manufacturing, installation, commissioning, training of the whole plant equipment, as well as delivering excellent after-sales services and technical support. Because the production process is automatically controlled and has reached the international leading level, we have such advantages as more stable production lines, more environmentally friendly production environment and more exemplary product quality. In addition, we have a patch of experienced, high-quality technical and management talents with over 100 employees, of which technical personnel account for 80% and R&D personnel occupy 10%. Over the years, we continue to explore grinding areas, makes in-depth research of the most advanced grinding, classifying and modifying techniques home and abroad, insist on research and development and innovation, thereby forming a set of mature ultrafine powder production with independent intellectual property rights for vertical mill, classifying, modifying and activation processes and to be used in the production of ultrafine powder.

In order to better serve customers, our company set a vertical mill production line in Pinggui District, Hezhou City, Guangxi, with a full set of secondary and tertiary classifying systems and modifying machine production lines. We also possess MALVERN-2000 laser diffraction particle size analyzer which was imported from the UK, ore whole composition analyzer and a full set of imported equipment. Concurrently we are building a modern, multi-functional key laboratory in Changping, Dongguan, with the purpose of providing customers with on-site grinding experiments and testing experiments regarding calcium carbonate, talcum powder, barium sulfate, wollastonite, dolomite, waste ceramic tiles, and pyrophyllite, etc.

A variety of equipment we produce has been widely used in preparing various kinds of ultrafine powder in different fields, including marble, calcite, talc, barite, dolomite, kaolin, wollastonite, limestone, feldspar, mica, gypsum, pyrophyllite, ceramic, aluminum hydroxide and magnesium hydrate. Our products are well received by customers nationwide.
